Research led by Children’s of Alabama and the University of Alabama at Birmingham (UAB) shows that magnesium sulfate does not improve neurodevelopmental outcomes in babies born very preterm between 22 and 24 weeks gestation.

Babies born during 22-24 weeks of gestation have a higher risk of neurodevelopmental impairment. While prior studies have found that magnesium sulfate helps prevent the development of cerebral palsy for babies born at later gestational ages between 24 and 32 weeks, this observational study led by Margaret Page, M.D., and Ashley Battarbee, M.D., in the UAB Department of Obstetrics and Gynecology, along with colleagues in the Department of Pediatrics, is one of the few studies of its kind to look at the use of magnesium sulfate for babies born at 22-24 weeks of gestation.

“This multicenter study led by Dr. Page and colleagues at UAB is important as it is the largest study designed to assess the two-year outcomes of infants born extremely preterm exposed to antenatal magnesium sulfate and/or steroids, two common treatments given before delivery,” said Wally Carlo, M.D., co-director of Neonatology at UAB and Children’s of Alabama and the Neonatal Research Network.

Battarbee says that OBGYNs cannot always stop a preterm birth, so they oftentimes need to shift their focus to how they can best prepare the baby to be born early.

“We consider interventions such as administering magnesium sulfate or antenatal corticosteroids to the pregnant patient to help improve outcomes for their baby after birth,” Battarbee said. “While the American College of Obstetricians and Gynecologists (ACOG) recently updated their guidance on corticosteroids for babies at 22 weeks, we did not have updated guidance on magnesium sulfate and wanted to explore this treatment further.”

The results of the recent study reinforce current national guidelines recommended by ACOG and the Society of Maternal-Fetal Medicine that do not recommend giving magnesium sulfate at 22 weeks and instead prioritizing antenatal corticosteroids to improve neurodevelopmental outcomes. Unlike magnesium, steroids have demonstrated benefit for infants born at very early gestational ages and remain the primary intervention when an early delivery is anticipated.

“There is not a lot of guidance on the use of magnesium sulfate in babies at this gestational age,” said Page, the lead investigator of the study. “Through this research, we were able to find that there was no benefit to using magnesium sulfate in addition to antenatal corticosteroids. This shows us that more treatment does not always equal better outcomes.”

Both Page and Battarbee emphasize that administering magnesium sulfate at that gestational age did not lead to any measurable increase in maternal or fetal harm in this study, but magnesium does carry known maternal risks, making it important not to use it without proven benefit. Additionally, using magnesium for neuroprotection in babies at these very early gestational ages when it is not effective may hinder future research in identifying interventions that truly make a difference.

This analysis was conducted using data from and in collaboration with the Neonatal Research Network, a large research network encompassing academic institutions across the United States funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

BRAIN Protocol Reduces Brain Bleeds in Very Preterm Babies

Dr. Vivek Shukla is a neonatologist at Children’s of Alabama.

After implementing new measures to protect the brain health of preterm babies, a multidisciplinary team at Children’s of Alabama at the University of Alabama at Birmingham (UAB) saw promising results that suggest a new protocol could prevent brain bleeds in preterm neonates.

More and more infants born before 29 weeks, 6 days are surviving, bringing greater attention to their long-term outcomes, particularly their neurological health. In their first few weeks of life outside the womb, these babies have a high risk of intraventricular hemorrhage (IVH), a type of bleeding in the brain. To reduce the risk of IVH and other brain bleeds, Children’s of Alabama neonatologists Vivek Shukla, M.D., and Maran Ramani, M.D., led a multidisciplinary team from the level IV regional neonatal intensive care unit (NICU) at the University of Alabama at Birmingham (UAB) in the development of a quality-improvement and management program for infants at high risk of IVH or other neurological complications. The team implemented the program, called BRAIN, in April 2018 with the goal of improving long-term neurological outcomes for these babies.

The interventions begin at birth and continue through the first week of life, which is considered the highest-risk period for IVH and other brain bleeds. Components of BRAIN include:

  • Using more sophisticated monitoring such as near-infrared spectroscopy
  • Protocolizing routine medication use within six hours of birth for most of babies—such as initiating IV indomethacin prophylaxis, which can reduce the risk of IVH—and limiting the use of saline boluses and bicarbonate
  • Reducing noise levels by carefully handling equipment and the incubator, minimizing incubator

door opening, reducing the intensity of alarms and promptly responding to them, avoiding conversations at the bedside as much as possible and using a soft voice if needed.

  • Standardizing infant positioning with an elevated head of the bed, avoiding putting the baby flat on the bed and getting help when turning the baby to ensure a neutral head position.

Of 127 babies tracked after implementing the neuroprotective protocol, none experienced a brain bleed or early death in the first week of life compared to 11 out of 99 (11%) prior to the intervention. The results were published in the Journal of Perinatology in July 2022. The work isn’t finished, however, with several additional approaches planned, including using machine learning and artificial intelligence to identify features that predict worse outcomes.

“All the congratulations go to my wonderful team, my wonderful mentors and my excellent colleagues here,” Shukla said. “This is not a single-person show. A lot needs to be done to ensure that preterm infants reach their best potential development.”
